The molecule can be represented as Hb in its unoxygenated form and as Hb O2 in its oxygenated form. One reason CO is toxic is that it competes with O, for binding to Hb: Hb O2(aq) + CO Hb CO(aq) + A G° = -14 kJ at 37°C (body temperature) What is the ratio of [Hb CO/[HbO2] at 37 °C with [O2] = [CO]?arrow_forward
